lions
Lions are the only cats that live in groups, which are called prides. Prides are family units that may include up to three males, a dozen or so females, and their young. All of a pride's lionesses are related, and female cubs typically stay with the group as they age. Young males eventually leave and establish their own prides by taking over a group headed by another male

dolphins
Their moans, groans, squeaks, whistles, and grunts can sound as if they're a heavy metal band. But bottlenose dolphins make their own kind of music. Many of the sounds they make could be imitated by holding a balloon tightly by the neck, then letting the air out faster and slower.

Coyotes
Coyotes in Los Angeles and Dallas? It's hard to imagine, but it's true. While populations of many other animals are shrinking, coyote populations are actually increasing. Coyotes once lived only in prairies and deserts of the western United States and in Mexico. Today they thrive almost anywhere in North America.
giants pandas
High in dense bamboo forests in the misty, rainy mountains of southwestern China lives one of the world's rarest mammals: the giant panda, also called the panda. Only about 1,000 of these black-and-white relatives of bears survive in the wild. Pandas eat almost nothing but bamboo shoots and leaves.
Wolves
The howl of a gray wolf isn't only a mysterious sound in the wilderness. Howling sends other wolves a message. It might mean "I'm here, where are you?" or "Stay away from my territory." Wolves live in groups called packs. The wolves' communication skills are very important to the pack's survival. Wolves work together to hunt, raise their young, and protect their territory.
Jaguars are the largest of South America's big cats and the third largest cats in the world. At one time jaguars roamed all the way to the U.S.-Mexico border, but jaguars are now only occasionally sighted in Texas and Arizona. Most jaguars are found in the Amazon River basin.
Gorillas
Youngsters tumble, climb, and run playing follow the leader. Another group plays a rowdy game of king of the mountain. Several adults watch the action, relaxing nearby. Is this a playground scene at school? No, guess again. It's a lush mountain forest high in the Virunga mountains of Africa, and the playmates are young mountain gorillas under the watchful eyes of their mothers.
Zebra
There is no mistaking what you're seeing when you spot a horselike animal with black-and-white stripes: it's a zebra. And each zebra has its own unique pattern of those distinctive stripes, just as humans have their own unique pattern of fingerprints.
Vampires bats
While much of the world sleeps, vampire bats emerge from dark caves, mines, tree hollows, and abandoned buildings in Mexico and Central and South America. They glide stealthily through the night air as they search for food. Like the legendary monster from which they get their name, these small mammals drink the blood of other animals for survival.
Elephants
When you think elephant, you probably think trunk. An adult African elephant's trunk is about seven feet (two meters) long! It's actually an elongated nose and upper lip. Like most noses, trunks are for smelling. But they're also for touching and grasping.
